如何显示 API 中的图片并在点击图片后将用户转到视频 link？科特林，改造

Question

我正在尝试在 recyclerview 中显示带有标题的视频缩略图

这是我的数据class:

data class PropertyItem(
    val id: Int,
    val thumbnailUrl: String,
    val title: String,
    val videoId: String,
    val videoUrl: String
)

这里是 list_item xml:

    <ImageView
            android:id="@+id/imageViewid"
            android:layout_width="0dp"
            android:layout_height="0dp"
            app:layout_constraintWidth_percent=".3"
            app:layout_constraintDimensionRatio="1:1"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            android:src="@drawable/ic_launcher_background"/>

主要活动：

class MainActivity : AppCompatActivity() {

    private lateinit var recyclerView: RecyclerView
    private lateinit var manager: RecyclerView.LayoutManager
    private lateinit var myAdapter: RecyclerView.Adapter<*>

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        manager = LinearLayoutManager(this)
        getAllData()
    }

    fun getAllData(){
        Api.retrofitService.getAllData().enqueue(object: Callback<List<PropertyItem>> {
            override fun onResponse(
                call: Call<List<PropertyItem>>,
                response: Response<List<PropertyItem>>
            ) {
                if(response.isSuccessful){
                    recyclerView = findViewById<RecyclerView>(R.id.recycler_view).apply{
                        myAdapter = MyAdapter(response.body()!!)
                        layoutManager = manager
                        adapter = myAdapter
                    }
                }
            }

            override fun onFailure(call: Call<List<PropertyItem>>, t: Throwable) {
                t.printStackTrace()
            }
        })
    }
}

适配器

class MyAdapter(private val data: List<PropertyItem>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>()  {

    class MyViewHolder(val view: View): RecyclerView.ViewHolder(view){
        fun bind(propertyItem: PropertyItem){
            val title = view.findViewById<TextView>(R.id.tvTitle)
            val imageView = view.findViewById<ImageView>(R.id.imageViewid)

            title.text = propertyItem.title
            Glide.with(view.context).load(propertyItem.thumbnailUrl).centerCrop().into(imageView)
        }
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val v = LayoutInflater.from(parent.context).inflate(R.layout.list_item, parent, false)
        return MyViewHolder(v)
    }

    override fun getItemCount(): Int {
        return data.size
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        holder.bind(data[position])
    }
}

所以我从数据 class 获取所有数据，但它不显示图像以及如何将 url 添加到图像视图以便用户可以单击图像并重定向到视频？

我正在学习本教程： https://www.codevscolor.com/android-kotlin-recyclerview-with-image

我做错了什么吗？

Answer 1

这段代码解决了我的问题

Picasso.with(activity)
            .load(countryList[position].thumbnailUrl)
            .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE)
            .networkPolicy(NetworkPolicy.NO_CACHE, NetworkPolicy.NO_STORE)
            .into(holder.thumbnailUrl)

我不得不使用 Picasso 而不是 Glide
